ga ementwitlrthe 111 s 28 on the curved loc ing plate 27 and wi l engagethe teeth of the gear 24. When the handle is so operated and is thenpulled downward the gear 24 will be rotated and through gear 23 willOperate the primary adding wheel. Fast t0 and forming part of the lever33 is a curved strip upon the face of which are numerals from 2 to 9inclusive and s0 arranged as to show through an opening 36 (see Fig. 1-)in the casin of the machine to serve as an 1ndex to the operator. Whenthe operator sees by the number appearing at said opening 36 that he haspu led the lever 33 to the desired extent he will then release the inchlever 31 which will (by its spring) be orced out of engagement with theteeth of the ear 24 and into engagement with one of the lbeking lugs 28thereby locking the lever 33 from returnmovement. Fast to the right handend of the rod 26 is an arm to whlch is loosely secured one end of alink 41 the other end being fastened to a relase key 20. From thisconstruction it will be seen that when the release'key 20 is pressed,the rod 26 will be rocked and the curved locking plates 27 will also berocked carrying the thereon out of engagement with the lug 29 of thespring catch 30 and allowing it to be returned to its normal position.To the lower end of each of the locking plates 27 is pivoted a springpawl which is so posltioned as to be moved into engagement with i theteeth of gear 24 when the rod 26 is rocked thereby preventing backwardmovement of the'gear 24 when the levers 33 are being restored to zero. g

It may be here noted that the movement of levers 34 is in each case onespace less than the number cans d to be indicated thereby by the rotaryindicator. If this was not the case the subsequent operation of the keylever 10 to effect the Wansaction ziiication would cause-an overregistrat .i as the depression of key lever 10 serves to add one unit tothe counter wheel '14. By the provision of a lever and a key for c 10hkind of transaction, it becomes possible to indicate not only the amountbut also the transaction characteristic. Clearly if the lever 34 wasrelied on to give the whole movement of the re ister, it would show theproper number on the indicator, but the indication of the characteristicwould he wanting. By the provision of a key which operates thetransaction characteristic indicator, it is possible. to employ thisindicator as a shield for the amount indicators, thereby compelling thedepression of the transaction key. The action of the lever will thencomplete the addition of the proper amount on the register. It will thusbe seen that the lever 34 must be connected to add one unit less than isindicated. It would, of course,-

possible to provide a permanent indicaugs 28.

tion above or below the amount indicators of the transactioncharacteristic, thereby dooperating devices for the movable elements ofthe reigistering mechanism.

Pivote to the lower end of each of the levers 33 is a rearwardlyextending link 46 the rear end of which is slotted to straddle ashaft47. The rack 48 formed on the inside of said slot is adapted to engage apinion 49 fast to shaft 47. Secured to shaft 47' is also another gear orpinion 50 with which meshes a rack bar 51 having rack teeth 52 at itslower end and rack teeth 53 at its upper end. The rack teeth 53 engage apinion 54 secured to an indicator 55. It

.is plain from this construction that whenever the lever 33 is moved theindicator 55 will also be moved to display a figure on its peripherycorresponding to the figure displayed at the opening'36. The lever 33and other connecting parts are restored by a rod 60 which extends acrossall of the links 46 and engages projections 61 thereon. The rod 60 issupported at each end by bell crank arms 62 pivoted on a rod 63 andextending forwardly over key coupler 12. V

, When thekey coupler 12 is raised it will swing the bell crank arms 62on their pivot and withdraw the rod 60 away from the projections 61 andwill tension a full stroke device to be described later. When the hecoupler 12 is lowered a spring 64 will roc the arms 62 and restore thelinks 46.

Resting on the rear end of each key is a tablet indicator 65. Thisindicator extends upward in front of the circular indicators therebyconcealing them. Each indicator 65 has a rectangular opening 66 and a.winged portion 67 and are so arranged as not to interfere with eachother during their operation. Upon the winged portion 67 are printedwords correspondipg to the words on the front of the keys 10. There aretwo openings 68 and 69 in the cabinet, the opening68 .is'to display theindication a pearing on the circular indicators the opening 69 being todisplay the words on the tablet ends. From the above description it willbe clear thatwhenever a key is de ressed the tablet indicator 65 will bee evated to, bring its rectangular opening 66 up to the opening 6,8 toreveal't e indicating figure on the circular indicator 55 and its win edportion 67 up to the opening 69 to di ay'- its indication of the kind ofarticle solfl their true indicating position by a plate 70 throng whichis attached to an arm 80 of a flash 81 to'be later described. This plate70 has in its upper end a V shaped notch 71 which enga with V shapedteeth in a semicircular 15k 72 fast to each indicator 55.

The above mentioned flash 81 is operated by a pin 82 on the release key20. This flash is intended to conceal all indicators during the timethey are being returned to their normal positions. 7

To insure a full upward stroke of the flash 81 and to hold it in itselevated osition until all parts are in their norma position themechanism shown in Fig. 4 is employed.

Fast to the shaft 63 is an n tendin arm-85 to the upper on of which ispivoted a laterally extending spring plunger 86. Loosely pivoted 'onshaft 63 is a sector 87' having teeth 88 on one of its edges adapted to.be en ged by a projection 89 mounted on the ash arm 80. Secured to theup or end of sector 87 is a collar 90 which passes the spring lunger 86.From this construction it will seen that when theshaft 63 is rocked thes rin of the plunger 86 will be tensioned an will force the teeth 88 ofthe sector 87 into engagement with the projection 89. As the flash arm81 is now raiaed the projection 89 will ratchet along theteeth 88 andwhen at the end of its upper movement the sector will s ring underprojection 89 thereby holdin the flash 81 in its elevated position untilt e; shaft 63 is rocked to its normal position again which only occ asall arts are restored to their norma hen the shaft 63 is so rockedthespring tension is released from the sector 87 whic will swin back to itsnormal osition allowing the flash to dro without t e projection 89contacting wit the teeth 88.

The complete operation of the machine is as follows: Suppose it isdesired to register and indicate one soda, the key marked Soda will bedepressed and its pawl 13 will move over the primary adding wheel onestep but without actuatin said wheel. The retaining bar 16 has in t emeantime latched the key in its upper position. The key coupler 12acting upon the bell crank wardly exlever 62 has tensioned the fullstroke device shown in Fig. 4. An indicator 65 bearin'g the word Soda lupon its winged portion 67 has also been raised to bring its rectangularopening 66 in front of the circular indicator thereby exposing thefigure 1 which is the normal position of said indicator and to bring itsworded indication up to the opening 69. The operation being now comleted the mechanism may be left in this con ition (with the key dcressed) to preserve the indication until t e depression of osition'.

vious tlperation and it is desired to register I and in icate 6 drinksof coffee as indicated in Fig. 1. The lever 34 is grasped and the muchlever 31 operated to disconnect the projection 29 from the curvedlocking plate 27 and force it into engagement with-the gear wheel 24.The lever 34 will now be pulled downward until the figure 6 appears atthe opening 36 (see Fig. '1) after which said lever is released allowingpro'ection 29 to be forced from the gear 24 an into engagement with oneof the lugs 28 of the plate 27 thereby holding lever 34 in its operatedposition. This movement of the lever34' will through the link 46,pinions 49 and 50, rock bar 51, and inion 54 set the indicator 55 tobring the gure 6 to indicating position. This movement has also throughprojection 61 and rod rocked the shaft 63 thereby tensionin the fullstroke device shown in Fig. 4. %low the key 10 marked Cofl'ee will bedepressed to raise the indicator and bring the indication as shown in Fi1 to view. If the release key 20 is now epressed all parts will berestored to than normal position including the lever 34 which isreleased by the rocking of rod 26 and plate 27 as previously define theinvention to the one form of embodiment herein disclosed, for it issusceptible of embodiment in various forms all coming within the scopeof the claims which follow.
